Compress Images Online and Convert Between WebP, JPG and PNG
A free tool that converts your images between WebP, JPG and PNG, compresses them and resizes them — in batches, even whole folders. All inside your browser with no uploads.
Images often make up more than half a web page's weight. Converting to WebP saves 25–35% at near-identical quality, improving your site speed and your Google ranking — page speed is a stated ranking factor.
A quality value of 80 is the sweet spot in most cases: large savings with a barely noticeable difference. Drop to 60–70 for large background images, and raise to 90 for fine detail.
How to use it — step by step
- Drop images or an entire folder (including subfolders).
- Pick the format: WebP, JPG or PNG.
- Set the quality, and a max width/height if you want to resize.
- Click “Start converting”, then download images individually or all as a ZIP.
Why processing inside your browser?
Your image never leaves your device. Most competing sites upload your photos to their servers to process them; this tool runs entirely in the browser. No upload, no account, no waiting and no limits — because your own device does the work.
Frequently asked
›Which format should I choose?
WebP for any website image. PNG for logos, transparency and print. JPG for sending via WhatsApp or email.
›Does it support transparent images?
Yes. WebP and PNG preserve transparency. JPG does not and will add a white background.
›How many images can I convert at once?
No limit. Try whole folders — processing happens on your device.
›Are my original files affected?
No. Originals are never touched; the tool produces new copies.
🔒 All processing happens inside your browser — no file leaves your device, no internet needed.
